⚡ The Ultimate Performance Solution

SyncBoost is not just another "lag clear" plugin; it is a comprehensive, professional-grade performance engine. Re-engineered for maximum efficiency, SyncBoost targets the root causes of server degradation—identifying CPU bottlenecks, memory leaks, and excessive entity overhead—allowing your server to sustain high player counts without compromising gameplay quality.

Why SyncBoost?

• ✨ Premium Experience: A stunning, modern GUI that brings visual elegance to server management.
• 🔧 Intelligent Automation: Dynamic algorithms that sense lag spikes and proactively adjust server load.
• 🗑️ Surgical Optimization: Reduce AI overhead, optimize redstone, and limit entities with pinpoint accuracy.
• 📊 Deep Monitoring: Real-time MSPT charts via interactive maps and detailed hardware benchmarks.
• ⚡ Asynchronous Core: Built to be ultra-lightweight, ensuring the optimization process never burdens your server.

[!IMPORTANT] SyncBoost is optimized for modern Minecraft infrastructure (1.20.5 - 1.21.x) but also fully supports legacy versions (1.17.1 - 1.20.4). Recommended Java 21, minimum Java 17.

🚀 Key Modules

SyncBoost is modular by design. Enable or disable features as needed via the in-game GUI or modules/ config files.

Module	Impact	Description
MobAiReducer	🔴 Very High	Optimizes creature pathfinding and AI behavior. Essential for farm-heavy survival servers.
EntityLimiter	🔴 High	Enforces limits on entity counts. Features Smart Mob Cap effectively balancing mob density based on server TPS.
LagShield	🔴 High	Active monitoring that triggers safety measures (e.g., pausing spawners) when TPS drops critically.
ExplosionOptimizer	🔴 High	Efficiently handles TNT and crystal explosions to prevent physics ticks from stalling the main thread.
ChunkAnalyzer	🔴 High	Scans and identifies problematic chunks with high entity/tile entity counts. Features interactive GUI with teleportation.
WorldCleaner	🟡 Medium	Periodically removes ground items. Features an "Abyss" system for item recovery via /abyss.
RedstoneLimiter	🟡 Medium	Detects and suppresses rapid-pulsing redstone clocks that cause TPS drops.
VehicleMotionReducer	🟡 Medium	Optimizes boat and minecart collisions, movement logic, and removes mineshaft clutter.
AbilityLimiter	🟡 Medium	Limits rapid Trident/Elytra usage to prevent excessive chunk loading.
HopperOptimizer	🟡 Medium	Reduces hopper tick rates and optimizes item transfer logic to minimize lag.
InstantLeafDecay	🔵 Low	Makes leaves decay instantly when trees are cut, reducing entity processing.
ConsoleFilter	🔵 Visual	Regex-based filtering to keep your server console clean and readable.
